a Claims. 1s4-15) of preparing petrolatum-like products prepared from solid waxes and hydrocarbon condensation products.

The relatively pared by mixing parailin wa tempts in the past have the paraffin plates or needles, products instead lucent properties and/or hydrogenation xes with oils. These atbeen unsuccessful because wax invariably crystallizes in large giving coarse non-homogeneous of the homogeneous and transinherent in petrolatums. I have now'discovered that petrolatum-like products can be made with parailln waxes or other waxes as a base and that these products do not crystallize in large plates or needles, but are homongeneous and possess excellent unctuous and translucent properties.

It is an object of my invention to produce an unctuous petrolatum-like product which is homogeneous and stable.

It is another object of my invention to obtain a petrolatum-like unguent from paraflln and other waxes which does not crystallize in large plates and needles and, which is homogeneous and of good color.

My investigations have disclosed that excellent stable petrolatum-like products can be prepared by mixing petroleum and/or other mineral waxes, such as paramn wax waxes such as ozocerite,

ceresin, carnauba and Montan waxes, with plastic resin-like products which are chemically stable and plastic at temperatures as low as 100 F.

Such products are oleflns, such as gaseous ing branched side ample, isobutylene fluoride, aluminum obtained by polymerizing isoor liquid oleflns containchains in the molecule, for exwith catalysts such as boron chloride, boron chloride,

zinc

chloride and other gaseous or solid volatile halides 0f the 2nd, 5th, 6th,

and 8th groups of .the

periodic system. Other similar products, such as polymerized normal butylene and hydrogenated rubber, may be used'in isobutylene product.

Stable, homogeneous products are obtained place of the polymerized petrolatum-like unctuous by mixing together 5 to 50% isobutylene polymer or other plastic resinous materials, 20 to 85% mineral oil and 10 to 40% parailln waxes and/or other mineral waxes.

Although any plastic resinous or resin-like material may be used to obtain the product of my invention, I prefer to use an isobutylene polymer having a molecular we ight of 2000 to 10,000. I

prefer to obtain the isobutylene polymer by treating isobutylene with boron fluoride at a temperature of about -80 F. under atmospheric pressure, and freeing the condensation product of boron fluoride by distillation or other suitable means.

I'lorthe purpose of illustrating my invention and not intending that it shall be limited thereby, the following examples are cited:

An excellent unctuous petrolatum-like product, which is homogeneous and stable, is obtained by 10 mixing together distillate parailln wax of about 180 F. melting point, 7 bright having a Saybolt Universal viscosity of about 1 seconds at 210 F., and 10% isobutylene polymer of about 4000 molecular weight.

Still another desirable petrolatum-llke product is obtained by mixing together 10% distillate parailln wax of about 180 F. melting point, 65% of a medicinal white oil having a are prepared by simply melting the wax and, after stirring in the required amount of oil and isobutylene polymer, allowing the mixture to cool to room petrolatum-like products of my invention is more transparent than paper treated with paraflln wax.

If desired I may medicate the unctuous petrolatum-like product prepared in the manner above described. I

the present invention has been de-' scribed in connection with details of specific examples thereof, it is not intended that these shall as limitations upon the scope of the as included in the acbe regarded invention, except insofar companying claims.

Iclaim 1. As a new composition of matter an unctuous product comprising from about 10% to about 40% wax, from about 5% to about 50% of a synthetic plastic resin obtained by polymerizing an olefin with a metallic halide catalyst at a low temperature, and at least about mineral oil, said constituents being combined in proportions to produce a product having petrolatum-like characteristics.

2. As a new composition of matter an unctuous product comprising from about 10% to about wax, from about 5 to about isobutylene polymer and at least about 20% mineral oil, said constituents being combined in proportions to produce a product having petrolatum-like characteristics.

8. As a new composition of matter an unctuous unguent comprising from about 10 to about 40% wax, from about 5 to about 50% isobutylene polymer and from about 20 to about mineral oil.

4. A petrolatum-like product comprising from 2,1as,41a

about 70% mineral oil having a viscosity of about 180 seconds at 210 F. and about 10% isobutylene polymer of about 4000 molecular weight.

6. As a new composition of matter an unctuous unguent comprising about 10% paraflin wax of about 180-185 F. melting point, about 65% medicinal petroleum oil having a viscosity of about 350 seconds at F. and about 25% isobutylene polymer or about 4000 molecular weight.
